Description

AD7841ASZ is an Analog Devices analog-to-digital converter (ADC). It uses a successive-approximation architecture to digitize an analog input into a digital word and comes in a RoHS-compliant 8-pin SOIC package (suffix ASZ). The device is designed for easy interfacing to microcontrollers and data-acquisition systems, typically offering single-supply operation and flexible input options (single-ended or differential) with a straightforward control timing interface. It’s suitable for instrumentation, measurement, and control applications where a compact, moderate-speed ADC is needed. For exact specification details—resolution, sampling rate, input voltage range, reference configuration, and electrical characteristics—consult the AD7841 datasheet. The ASZ suffix simply denotes the packaging version; always verify current packaging and part options in the latest documentation.
